PORTABLE DOOR FASTENER.

Application. led January 18, 1922 Serial No. 530,194.

it lrnown that l, Winnaar T. ABBOTT, a citizen of the United yStates,residing at Columbus, in the county of Franklin and the State of Chio,have invented certain new Vand useful Improvements in Portable DoorFasteners, of which the following is a speci- :'ication, reference beinghad therein to the accompanying drawing.

My present invention relates to certain new and useful improvements inportable door fasteners, and particularly to that class of doorfasteners which are adapted to be carried in the satchel of a travelerand to be applied to the room door in a `hotel or lodging house toinsure the occupant of the room against intrusion from without.

lt is the especial object of this invention to produce a device of theclass described which shall be simple of construction, convenient ofapplication, and reliable in operation.

The means by which l attain these objects is fully set forth in thefollowing specication, and illustrated in the accompanying drawingr4 ofwhichl is a sectional view taken through the edge of' a door and itsjamb, illustrating the relation of my improved door fastener to the doorduring use.

Fig. 2 is a perspective view of my improved door fastener in assembledrelation. A Figs. 8, l and 5 are details of the several elements whichgo to make up the device illustrated in Figs. l and2.

Lilie numerals refer to similar parts in the several figures.

As illustrated in the drawings my improved door fastener comprises anelongated plate l adapted to be inserted between the edge of a door 2and its jamb 3 when said door is in closed position. Formed on the innerend of the plate l is a hook` like projection l adapted to enter theaperture in the keeper 5 which is commonly supplied to receive the latchbolt of the customary door lock. Formed in the plate l and extendinglongitudinally thereof is a slot 6 through which projects the flange 7formed along the central longitudinal line of the plate 8 whichconstitutes a rider adapted to slide longitudinally along one face ofthe plate l. The proportions of the parts are such that when the riderplate 8 is in contact with the plate l. the flange 7 will project tosuch a distance through the slot 6 that it may be placed contactl withthe face of the door 2, as illustrated in Fig. 1. Means is provided toprovent outward movement of the rider 8 in the wedge 9 which is adaptedto engage the flange 7 and a reflened fold 10 formed at the outer end ofthe plate l. `When the wedge 9 is in position under the fold l0 itsopposite edge enters the notch l1 formed in the outer edge of the liange7 thereby insuring against accidental withdrawal of the flange 7 fromthe slot 6.

ln operation the plate l is placed in position against the door jamb 3with the progection il extending into the aperture ofthe keeper 5, andthe door closed against it. The

rider 8 is then placed in position with the 7 projecting through theslot 6 and extending towards the door 2. The wedge 9 is then inserted inthe notch 1l and under the fold l0, and is moved laterally of the platel until the keeper flange 7 is firmly pressed against the face of thedoor. When these parts are thus positioned the door 2 will be securelyheld in 'closed position, thereby insuring the occupant of the room fromintrusion from without.

llVhat l. claim as my invention is l. ln a device of the classdescribed, the combination with an elongated plate insertable betweenthe edge of a door and its j amb having a hook at one end adapted toengage said jamb and a refleXed fold at its other end, of a riderslidable longitudinally of the plate and adapted to engage the face ofthe door, and a wedge adapted to engage said rider and said refleXedfold to prevent movement of said rider relative to said plate as and forthe purpose set forth.

2. In a device of the class described, the combination with an elongatedplate insertable between the edge of a door and its j amb and having` ahoolr` at one end adapted to engage said jamb and a refleXed fold at itsother end, of a rider slidable longitudinally upon the face of the plateand having a flange adapted to project through a longitudinallyextending slot therein to engage the face of the door` and a wedgeadapted to engage said flange and said reileXed fold to prevent movementof said rider relative to said plate as and for the purpose set forth.

In a device of the class described, the combination with an elongatedplate insertable between the edge of a door and its amb, and having ahook at one end adapted to enga-ge said jamb and a relexedfold at itsother end? of a Fidel' Slidahle longitudinally along the falce of theplate and having a lange adapted to project thiough n longitudinallyextending slot theen to engage the face oi the door, and a Wedge adaptedto engage a notch in seid flange to prevent. its Withdranf'al from saidSlot as and for the purpose set forth.

4l.A ln a device of the class described, the combination with anelongated plate insertahle between the edge of a door and its jamb andhaving a hook at one end adepted'yto Lelieel engage said and ieexed foldat its ori-hei end7 of aridei' slidable along one face of seid plete andhaving a flange adapted to pioject through e. longitudinally extendingslot thefein to engage the fece of the door, and a Wedge adapted toengage said Piange and said reexed fold to prevent movement of saidrider relative to said plete as and for the pnpoee set forth.
